Firmiana colorata (Colored Sterculia)

Firmiana colorata, commonly known as scarlet sterculia, is a deciduous or semi-deciduous tree in the Malvaceae family, native from the Indian subcontinent through mainland Southeast Asia. It develops a spreading crown and large, soft-textured leaves that are broadly heart-shaped to palmately lobed, often with three to five prominent lobes. One of its most striking features is flowering on nearly bare branches after the leaves have fallen. Dense clusters of small scarlet to orange-red flowers create a brilliant display against the branches before new foliage develops. The fruits consist of papery follicles that split open when mature, exposing the seeds along their margins.

Firmiana colorata grows best in full sun and warm tropical to subtropical conditions. It adapts to various soils provided drainage is good and established trees tolerate a pronounced seasonal dry period. Its combination of large decorative foliage and vivid leafless-season flowering makes it an attractive specimen tree for spacious gardens and tropical landscapes. Young plants benefit from regular moisture while becoming established. Propagation is primarily by seed. It is best suited outdoors to approximately USDA Zones 10-11 and should be protected from significant frost.
